TNELSON BINGHAM, OF ERIE, NORTH DAKOTA DETACHABLE SURFACE-PACKER.

Specification of Letters Patent.

Application filed June 29, 1912. Serial No. 706,752. i

To all whom it may concern .1

Be it known that I, NnLson BlNGHAM, citizen of the United States, residing at Erie. in the county of ,(ass and State of North Dakota, have invented certain newand useful Improvements in Detachable Surface-Packers, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to surface packers,

and has for its object the production of a simple and eflicientsurface packer, and a detachable shield therefor, whereby the shield constitute a surface, and sub-surface packer.

Another object ofthis invention is the production of a simple and efficient packer casing or shield which may be quickly and efficiently secured to-the packer. lVith these and other objects in view, this invention consists of certain novel construc-' tions, combinations, and arrangements of parts, as will be hereinafter fully described 25 seen that the'ordinary disks 1 maybe employed, which have beveled outer faces, as indicated in- Figs-2 and 3, and between these -disks 1 are positioned sub-surface disks 2.

.The disks 1 are supported upon a supporting shaft and, the sub-surface packing disks 9 are provided with sockets i, within which sockets are placed filling collars 'lhecasing or protector ti is placed upon the surface and subsurface packers 1 and 2, as indicated in Fig. 2, and this protector 6 comprises a primary and auxiliary section, as

indicated in Fig, 1 Each of the sections is provided with a substantially V-shaped portion 7, which fits over the sub-surface extending spaced packing members 8 direct from the substantially V-shaped portion 7,.

indicated in Fig. 2. The end packing. member 9 of each section is formed L-shaped in cross section and the abutting faces of these members 9 are held togetherby means of a bolt 10. In'this manner, it will be seen Patented Mar. 4:, 1913.

that the primary and auxiliarysections of the protector will be firmly held upon the disks.

From the foregoing description, it Will be readily seen that. a very sim 1e and eflicient device has been produce which may be readily attached to the surface and subsurface packer in such a manner as to allow both the surface and sub-surface of the soil to be efiiciently packed. It will be further seen that a simple protecting casing has: i

been produced which may be readily detached from the packer disks,

The outer edges of disks 2 are smooth and it will, therefore, be seen thatthe spaced packing members 8 will constitute an efiicient packing means for the soil'espe'cially where the packer is used in soft, sandy soil.

By havingthese spaced packing members so carrled upon the smooth outer faces of the disks 2, it will Joe-seen that the packer will very efliciently operate upon soft soil and will not merely form a hard crust upon the surface; of the soil as" would be the case if the entire surface of the packer, were smooth. I

Of. course it s'houldbe understood that the present device may be' used with or without the casing or protector 6,'thereby allowing the disks 2 to be used as a surface packer and .the'disk 1 to be used as a subsurface packer. These, disks maybe employed in this manner without the casing or protector '6' when using the packer upon hard soil, but where thedevice is to be used upon soft or sandy soil the casing or protector (5 is placed upon the disks 1 and 2. Itshouldv be understood, as illustrated clearly iii-Fig.3, that when the casing "or protect-or 6 is placed upon thedisk'l, the

disk 1 will be entirely or completely cov-' ered, thelugs S extending upon either side thereof andoverlmnging the upper edges of the'disks 2."

What is claimed is 1. Afdevice ofthe class described comprising: a si1b-Surfacepacking disk,"a-surg face packing disk vpl'aced upon each side of packing disk 1, and a plurality of laterally 7.

said sub-surface packing; disk, said surface packing disks" provided. with socket-s upon said sub-surface packin'gdisks and provided with spaced packing membersv overhanging the edges of said surfacenpacking disk.

A device of the classjdescribed 'com prising a subsurface packing disk, 21 pair of surface packing (iiFkS, a sectional casing posxiinnvd upon said packing disks, ruck sectimi fitting over said subsurface packing disk and tcrminuiing in iaiemliy PXtQDK l" im: Spflflfil packing members, each section 1 said casing provided with a packing member at each end L-ShRDQd in cross sec- Sum.
